TEMPORARY SNOW FENCE
To provide a temporary snow fence that can be constructed in a short time without requiring a lot of manpower and skill.SOLUTION: A temporary snow fence comprises: main pillars erected at prescribed intervals along one line; a net stretched between the main pillars; supporting pillars for supporting the main pillars obliquely from below; and piles for fixing lower ends of the supporting pillars to the ground. The net has bag parts formed at least on upper and lower edges, and comprises locking metal fittings at both ends. The net is inserted into the bag parts and stretched in a nearly vertical position by two horizontal bars laid horizontally between the two main pillars. Fastening screws are planted at the specified height of the supporting pillars. The locking metal fittings have circular holes large enough to allow heads of the fastening screws to pass therethrough, oblong holes smaller than the diameter of the heads of the fastening screws and wider than the diameter of shafts, and extending horizontally above the circular holes, and bell-shaped holes with connection parts between the circular holes and the oblong holes. The locking metal fittings are joined with the shafts of the fastening screws positioned in the oblong holes.SELECTED DRAWING: Figure 1
【課題】多くの人手と熟練を必要とせずに短時間で構築することができる仮設防雪柵を提供する。【解決手段】１本の線上に沿って所定の間隔で立設された主柱と、主柱間に張設されたネットと、主柱をそれぞれ斜め下方から支える控柱と、控柱の下端を地面に固定するための杭とを有する仮設防雪柵において、前記ネットは少なくとも上縁および下縁に袋部が形成され、両端に係止金具を備え前記袋部に挿通され２本の主柱間に水平状態で横架された２本の横棒によってほぼ垂直な姿勢にて張設され、控柱の所定高さ位置には締結用ネジが植設され、係止金具には、締結用ネジの頭部が挿通可能な大きさの円形穴と締結用ネジの頭部の径よりも小さく軸部の径よりも大きな幅を有し円形穴の上方にて水平方向に沿って延設された長穴と、円形穴と長穴を接続する連通部を有するだるま穴が形成され、係止金具は締結用ネジの軸部が長穴内に位置した状態で結合されるようにした。【選択図】図１
